Why is the speed of ships measured in knots?

For a long time, to determine the speed of ships, a sector log was used - a triangular board with a rope tied to it, on which knots were tied at the same distance. The board was thrown overboard, the time was recorded (usually half a minute) and they counted how many knots the rope carried by the lag would unwind while the ship was moving forward. If the distance between the knots is a multiple of a nautical mile (for example, 1/120 of a mile), then you can immediately determine the speed in miles per hour. This unit of measurement is called the "knot". Modern instruments for measuring the speed of ships are more advanced and work on other principles, but they still indicate it in knots.

Random interesting fact from the Great Encyclopedia:

When did restaurants appear?

You probably think that food is cooked to taste better. In fact, it helps the body absorb it better. Cooking also keeps us healthy because it kills bacteria and other micro-organisms that can harm us.

No matter how delicious mom cooks, sometimes we want to go to a restaurant (if, of course, we have enough money). And not because you want to eat something delicious. The main thing is to change the environment and communicate with people. Restaurants have not always existed. There were taverns where people gathered to talk, drink and maybe eat something. In London, such establishments were called master's shops.

At first, the workers of these shops cooked the meat that the visitors brought with them. Later they switched to their own products. It already looked like a restaurant. Such master shops existed until the XNUMXth century! The tavern in London was the first place where you could eat cooked food every day at certain hours.

Often such taverns became clubs. This happened in the XNUMXth century. In the middle of the XNUMXth century, citizens of different incomes developed the habit of dining not at home, but in taverns. Most taverns offered meals for a shilling or less. These dinners included wine and even ale.

Taverns have become meeting places for famous people. Shakespeare became a regular at the Mermaid Tavern in London. By 1765, coffeehouses were also springing up in London. There you could find coffee, tea, chocolate, which were a novelty, a curiosity at that time. Sometimes there you could eat something more substantial.

In 1765, a man named Boulanger opened an establishment in Paris that sold snacks and cooked meals. He called this place a restaurant. That was the first time the word was used. The establishment was a success, and many similar ones opened soon after. Within a short period of time, restaurants have spread widely throughout France. The word "restaurant" was used in England until the end of the 1683th century. In the United States, the first restaurant opened in Philadelphia in XNUMX. It was called "Blue Anchor".

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Power generator in contact lenses 15.12.2016

Samsung patents a power generation system for smart contact lenses.

It is assumed that a special piezoelectric layer will be introduced into the lens structure, thanks to which the product will be able to generate electricity due to slight deformation during natural movements of the eye and eyelids.

It is proposed to use a tiny capacitor to store the generated energy. The generated electricity will power the electronic circuits built into the structure of the lenses. It can be any sensors or means of displaying information.

Recall that Samsung has already registered a patent for the manufacture of contact lenses with a system that projects an image directly into the eyes of their owner. It is assumed that such a solution can provide a more natural way to implement augmented reality technology than, say, smart glasses.

We add that "smart" contact lenses are also developed by Google. The search giant is considering using such products to measure temperature, pH, alcohol content, cholesterol levels, and more. The main purpose of Google smart lenses should be to measure glucose levels, which should help people with diabetes.
